CStarRating is based on jQuery Star Rating Plugin. It displays a list of stars indicating the rating values. Users can toggle these stars to indicate their rating input. On the server side, when the rating input is submitted, the value can be retrieved in the same way as working with a normal HTML input. For example, using
$this->widget('CStarRating',array('name'=>'rating'));
we can retrieve the rating value via $_POST['rating'].
CStarRating allows customization of its appearance. It also supports empty rating as well as read-only rating.
